"This was a very strong quarter for Google," Eric Schmidt, chief executive for Google, said in a statement. "We continue to execute well and we have been able to take full advantage of the growth in online advertising."

Revenues generated from Google's partner sites through its AdSense programs contributed $584 million, or 47 percent of revenues, a 75 percent increase over partner-related revenues a year ago.
As of March 31, Google had 3,482 full-time employees, up from 3,021 as of the end of the fourth quarter last year.
